These data (Table F.1) are part of a larger data set used by Fielding and Haworth (1995) to investigate the performance of bird-habitat models. They relate to the core area, the region close to the nest, of golden eagle Aquila chrysaetos, in three regions of western Scotland. Eight habitat variables were measured for each range. The values are the numbers of four-hectare grid cells covered by the habitat.
The box plots in Figure F.1 indicate that most of the variables, within the regions, have reasonably symmetric frequency distributions, although region two in particular has a number of unusual values (outliers). There are obvious differences between the regions for all eight variables.
